Excess Soil: A Comprehensive Guide

Ontario Excess Soil Regulation 406/19 (On-site and Excess Soil Management, and Rules for Soil Management and Excess Soil Quality Standards) establish criteria for the on-site management, transportation and off-site reuse and disposal of excess soil. These criteria clarify when excess soil can be reused for a beneficial purpose at a reuse site and when it must be disposed of as waste at an approved waste disposal site, such as a landfill. The improper management of excess soil may result in negative impacts on soil, groundwater, landscapes, human health, and environment for local natural ecosystems. Following O.Reg.406/19 will ensure the implementation of excess soil management processes for reuse or disposal for regulatory compliance, which may also reduce the excess soil that ends up in landfills.
